CSR64215 Bluetooth 4.2 /5.0 Lossless Stereo Audio Receiver Board for Pre-amplifier APT-X Wireless WiFi Music Receiver Module DC 6-36V

1.Description:

It is a 5.0 Bluetooth receiver board.This module is suitable for refitting audio equipment such as power amplifier,power amplifier board DIY,power amplifier pre-amplifier and so on.It transforms the traditional wired transmission into a wireless Bluetooth transmission.The module uses the CSR64215 high-fidelity Bluetooth chip.The Bluetooth 5.0 version ensures high-speed data transmission and enables the audio data to be transmitted to the analog power amplifier without loss.To achieve wireless HIFI-level sound quality.The module supports APT-X lossless reception,and the sound quality reaches the CD level.It is a truly lossless Bluetooth receiver module.

2.Feature:

1).The module receives and outputs standard single-ended analog audio signals for Bluetooth.

2).It can directly provide audio signals to the pre-stage or post-stage analog power amplifiers without the need for additional DAC decoders.

3).In order to facilitate the modification needs of DIY friends,the module is designed with an AUX input,which is convenient for external linear audio.

4).NEC high-precision relay is used to switch between AUX and Bluetooth.

5).The AUX input is not processed by any chip,and the output is switched directly by the relay to ensure the lossless output of AUX audio to the power amplifier.

3.Parameter:

1).Product Name:5.0 Bluetooth Receiver Board

2).Input Voltage:DC 6V-36V

3).Input Current:500mA

4).Bluetooth Protocol:Bluetooth 5.0

5).Supporting Agreement:APT-X,A2DPv1.3,AVRCPv1.6,HFPv1.6,HSPv1.2,DIv1.3

5).Work Temperature:-25℃~85℃

6).Work Humidity:5%~95%RH

7).Size:65*33*11mm

4.Interface Description:

1).DC power input interface:GND is the negative pole of the power supply,and +12V is the positive pole of the power supply.

2).AUX audio interface:LINE_INR right channel input,GND common ground,LINE_INL left channel input.

3).Audio output interface:R_OUT right channel output,GND common ground wire,L_OUT left channel output.

4).Audio switching relay:to ensure sound quality transmission and working life.

5).Onboard Bluetooth antenna:It is used to receive signals and keep it open and unobstructed.If the module is installed in a metal chassis,an external antenna (2.4G antenna like router) is required to ensure complete signal reception.For example,no external antenna is needed on the side of plastic or wooden housing.

6).CSR64215 Bluetooth solution:Support APT-X lossless signal reception.
